Descriptive Report of the Patent for "Portion Capsule with Identifier". r
The present invention relates to a portion capsule for producing a beverage, which comprises a base element which has a cavity within which a raw beverage material is provided and which is closed by a membrane attached to the base element. .
Such portions of capsules are well known and are being launched on the market in an abundant variety.
As these capsules are often quite similar, it is possible that 'capsules from one manufacturer are used in a coffee machine designed by another manufacturer.
_ bricante, although these are not suitable for it.
This can result in significant safety problems and / or the coffee machine could be damaged. the object of the present invention is therefore to provide a 15 portion capsule which is only suitable for a specific coffee machine. the object is achieved according to the present invention by a portion capsule for producing a drink, which comprises a base element which has a cavity within which a raw drink material is provided and which is closed by a membrane attached to the base element, within which there is an identifier, which allows the respective portion capsule to be individualized.
The present invention relates to a capsule for producing a beverage or food product, which comprises a base element that has a cavity within which a raw beverage material is provided. 25 Such capsules are, for example, made of plastic, natural materials and / or biodegradable materials and substantially have a base element, specifically a deep base element, that is, it is substantially designed trunk-conically or cylindrically .
The raw beverage material is disposed within the cavity of the portion capsule and is extracted and / or dissolved in a liquid, specifically water.
After the raw beverage material has been filled into the cavity, the base element is usually sealed by a membrane.
Specifically, the membrane is located
"" located on the opposite side of the bottom of the base element.
The membrane can be made of the same or different material as the base element and is substantially attached to the base element using a seal and / or adhesive bond.
In addition, the cavity could contain one or more embedded elements 5, such as, for example, a filter, a nonwoven, a felt, a closing device and / or something similar to these.
For the case where a nonwoven and felt are disposed within the cavity, these are preferably interconnected.
The nonwoven and / or felt can be made of several layers in such a way that the layers can differ in the type of
10 your starting material and / or your preparation.
Furthermore, the membrane and / or the "plug" can be provided with a plurality of recesses (holes). According to the present invention, it is provided that the portion capsule has an identifier that allows the respective capsule to be individualized. portion.
In the context of this invention individualizing means that the respective portion capsule can be assigned to a group of capsules that are suitable for the coffee machine preferably.
It is not necessary for the coffee machine to be able to specify and / or identify the serving capsule.
In fact, it is much more important that the coffee machine associates the portion capsule with a group of portion capsules, which is suitable for the coffee machine.
Specifically, individualizing means that these portion capsules that are not suitable for the coffee machine cannot be inserted and / or fall directly through the holder, which is designed for the portion capsules in the coffee machine, and / or the machine of coffee operates only with the corresponding serving capsules.
Preferably a sensor / detection system manipulates the identifier and compares it with a reference stored substantially.
Preferably, the coffee machine, specifically the water supply pressure pump, will be activated if the detected identifier matches the reference.
Otherwise, the coffee machine will not start operating.
Preferably, the detection system 30 is located in the region of the product trough of the coffee machine designed for the portion capsules.
According to another preferred embodiment of the invention, the detection system can be placed in the region
.
"of the preparation chamber. Another possible embodiment of the invention provides that the identifier prevents the portion capsules from being inserted into the
W coffee machine. Alternatively or in addition, a medium, specifically a mechanical medium, more preferably one or more gear wheels, can be added to the product chute in order to ensure that the incorrect portion capsule cannot be inserted on coffee machines passing through the product trough. The identifier is preferably composed of areas of surfaces that have different optical properties, for example, reflection. These 10 surfaces can be located on the membrane, the side wall "and / or the bottom of the portion capsules. Preferably, the portion capsule has at least two areas which differ in their optical properties,
W for example, the reflection characteristics. Detection of a recess and / or a bulge is also preferred. Preferably, recesses and protrusions alternate and / or at least two recesses or protuberances are separately coffered from each other. Especially it is possible that the recess and / or the protrusion forms a gear wheel that is attached to the outer edge and / or at least partially extends to the portion region of the wall of the capsule. The low profile and / or the protrusion can be produced by any method of forming, for example, by deep drawing, preferably. Furthermore, the recess can be achieved by removing materid. Specifically, material removal can be achieved by puncturing or using a laser on the condition that this processing does not damage the barrier layer 25 within the portion capsule material, which prevents moisture or aroma from escaping from the capsule. portion and / or water vapor or oxygen enters the capsule. The reading of the identifier, which is encoded in the recess or protuberance, can be a result of a mechanical and / or optical method, for example. Alternatively or in addition, the identifier can be used to prevent the serving capsule from being inserted into the coffee machine. This applies specifically to the product chute. For example, it is possible to design a portion capsule that comprises a ring gear that is placed over its circumference and is com- "" ~ -
compatible with another ring gear, which is placed inside the product rail m.
If the ring gear of the product chute only rotates to a corresponding ring gear of the portion capsule and at 5 its rotation allows the portion capsule to pass, only the portion capsules equipped with the appropriate ring gear will pass through the insertion.
In accordance with a further subject of a preferred development of the present invention, the identifier may be included in the blank.
Preferably, the identifier is a layer or a partial layer "of the membrane.
Such identifiers can be an optically detectable material, for example, a fluorescent material.
Furthermore, the identifier may be designed with layers made of metal or ferrous metal or strips made of metal or ferrous metal inside or on the membrane, respectively.
Preferably the identifier is a machine-readable print. This is done with a print in a color approved for food, preferably.
Fluorescent materials such as paper or printing materials, whose optical properties change under the influence of temperature, are also preferred.
Preferably, the impression is a barcode, a logo or an affinity.
In accordance with an additional subject of a preferred development of the present invention, the identifier is an electrically conductive section, which can be co-focused over the entire portion capsule, but is located on the side wall, the edge and / or the bottom preferably.
The electrically conductive section, which is inserted into the coffee machine, can become part of an electrical circuit and therefore causes a measurable change, which leads to the identification of the respective portion capsule.
In an additionally preferred embodiment, the identifier is a section made of a ferromagnetic material.
Another construction version gives preference to an RFID chip being the identifier.
»
If the portion capsule is customized according to the invention, the portion capsules that are not in line with the coffee machine «will be prevented from being inserted into the coffee machine.
Furthermore, it is possible that the identifier allows to identify the capsule of localized portion
5 inside the preparation chamber in such a way that the beverage or food production process can be controlled, for example, by adjusting the temperature, pressure and / or the amount of water.
According to a further subject of a preferred development of the present invention, the portion capsule material is weakened.
l Acid in the bottom area caused by selective material removal, for example, "using a laser.
Weakening is provided to pierce the portion capsules using a mandrel.
This procedure is necessary - for the preparation of the drink.
As the material is weakened in the section, which is treated with a laser and is supposed to be drilled using the mandrel, the
15 degree of force required to pierce the portion capsule is reduced.
The spindle of such coffee machines is usually equipped with a force limitation that limits the force, which is dedicated to pressing the spindle against the bottom of the portion capsule.
This preparation prevents the portion capsules that do not have an appropriate weakening from being used
20 used in such a coffee machine.
Consequently, the weakening represents another type of identifier.
In accordance with an additional subject of "a preferred development of the present invention, the portion capsule has an edge region, which is preferably attached to the base element.
Preferably,
25 edge is located opposite the bottom area of the base element.
After the raw material has been filled into the portion capsule, a membrane can be attached to this edge region, for example.
Furthermore, the rim can also be designed to guide the portion capsule into the chute in order to position the portion capsule within the preparation chamber 30 appropriately.
At the same time, it is possible to use the edge surface for stop and / or sealing.
Preferably a provision is made for the portion capsule to have
L - means for locking by adjustment, locking by friction and / or detection in the edge region. The means for locking by adjustment and / or locking by friction can be used to activate a complementary mechanism, which is located inside the coffee machine, in order to allow the insertion of the portion capsule in the coffee machine and / or to connect a sensor, such as a gear wheel, that transmits a signal to a control unit depending on whether the portion capsule corresponds to the coffee machine or not. Alternatively or in addition, a detector can identify the means for locking by adjustment, locking by friction and / or detection in order to check whether the portion capsule is suitable for the respective coffee machine. Preferably, the means for setting locking, locking
X _ by wheel-drive and / or gear detection, is one which is located in gear, or one specifically in the outer area segment of the edge region. The teeth of the gear wheel or the gear wheel segment 15 can be formed in any commonly used shape, which is known, for example, by a gear manufacturing specialist. Preferably, these teeth are provided to be triangular, rectangular, square or wavy. Preferably, there is a sealing surface which is arranged on the inner side in relation to the gear wheel or the gear wheel segment. Another technology of the best modern preferred technique is a portion capsule for producing a beverage, which comprises a base element substantially designed conically or cylindrically, 25 which has a cavity within which a raw beverage material is provided and the which is closed by a membrane attached to the base element with the base element having a wall region and the base element having a bottom area, which is preferably located opposite the membrane, with the wall having several slots and the slots at 30 are located between the membrane and the bottom area covering the wall region along its height at least partially. The grooves can also be located in the edge region, specifically over the area
"outside of the edge region. This portion capsule has the advantage over the portion capsule according to the technology of the best modern technique that, for example, the grooves reinforce the wall region of the base element. on the one hand these grooves make the portion capsule more stable in the sense of mechanical forces and prevent the portion capsule from deforming and warping, specifically. The arrangement of the grooves, which are located in the wall region, further improves the performance of the portion capsule while the extraction liquid flows through it inside the preparation chamber, since the arrangement of the grooves, specifically those that partially extend over the wall region between the membrane and the bottom area, increase the quality and the reliability of the extraction process
W significantly. According to the invention, another advantage is that the thickness of the base element can be reduced, because the use of grooves improves physical stability. The production of the portion capsule is therefore much less expensive and more environmentally friendly. On the other hand, the grooves reduce or prevent contact between the portion region of the portion capsule and the wall of the preparation chamber. As a result, ejection or removal of the capsule portion from the preparation chamber is made easier. Another advantage of using a plurality of grooves is that the flow of the extraction liquid, which flows along the base element within the cavity, can be optimized by choosing a groove structure that is capable, for example, to generate on the one hand a better or stronger turbulence in the extraction liquid or on the other hand a more uniform (laminar) flow of the extraction liquid in the wall region. Control of the liquid can be achieved by the structure of the grooves themselves or by using a simple means additionally. A stronger turbulence compared to that known in the best modern technique has the advantage that no unintended or casual main flow is formed within 30 of the raw materials. Instead, the extraction liquid flows equally through the raw material within the entire volume. So the extraction process is much more efficient and can be controlled more precisely and reproducibly.
m mind.
Specifically, the raw material can be coffee powder (specially ground roasted coffee), chocolate powder, powdered milk, tea or similar.
Alternatively, it is conceivable that the raw material is a beverage extract, 5 such as instant coffee, for example.
Specifically, the grooves are recesses and protrusions, which are preferably directed along a major extension and are preferably extended along the long edge of the wall portion or edge of the edge region.
More preferably, the grooves are formed as webs and / or notches.
A gear wheel, for example, can be "obtained by the grooves.
Therefore, the grooves are part of the base element wall, optionally located on the inner side facing. cavity and / or on the outside facing away from the cavity.
According to a preferred embodiment of the present invention, the grooves are provided to form an identifier that allows the portion capsule to be individualized.
In the context of this invention, individualizing preferably means that the respective portion capsule can be assigned to a group of capsules that are suitable for the respective coffee machine or the machine that produces a drink.
It is not necessary for the coffee machine 20 or the device to produce a beverage to be able to specify and / or identify the serving capsule.
It is more important that the device _to produce a beverage, specifically a coffee machine, associates the portion capsule with a group of portion capsules, which is suitable for the respective device for producing a beverage, specifically a coffee machine. coffee.
Specifically, individualizing means that those portion capsules that are not suitable for the coffee machine (or for the device that produces the drink) cannot be inserted and / or directly fall through the holder, which is designed for the capsules portion in the coffee machine (or in the device that produces the drink), and / or the coffee machine (or in the device that produces the drink) operates only with the corresponding portion capsules ("appropriate portion capsule" ). Specifically, individualizing means that the coffee machine or the
=
"device producing the beverage will not operate properly in its intended use, if the portion capsule used is not customized according to the invention.
Preferably a sensor / detection system, attached to the coffee machine or the device that produces the drink, records the identifier 5 and substantially compares it with a stored reference.
Specifically, it is possible that such an identification process is based on a mechanical adjustment, especially an adjustment of a gear wheel or a contour comparable to a gear wheel, which is stuck in the device that produces the drink or in the coffee machine and interacts with the 10 portion capsule.
It is preferred that the device for producing the beverage or "the coffee machine will only operate if the identifier matches the reference or the mechanical settings match each other.
In this case, the device for producing the drink specifically begins to operate, specifically activating a pressure or water pump.
The means for detection or mechanical adjustment is preferably located in the region of the product chute. .- to or in the region of the device for producing the drink.
Tenderly, the identifier or mechanical adjustment can prevent a capsule of inadequate portion from being inserted into the device to produce the drink.
A portion capsule, which is designed according to the invention, makes it possible that the portion capsule that is not designed for the device for producing a drink cannot be inserted therein.
In addition, the Identifier allows the device to produce the drink, especially the coffee machine, to specify the type of serving capsule and thereby control the process of producing the drink and food by adapting, for example, , pressure, temperature and / or water quantity.
According to a preferred embodiment added to the present invention, it is provided that at least part of the grooves and at least one subarea parallel to the main plane of the membrane is in the form of a gear wheel. According to the present invention, it is an advantage that it is possible to increase the stability of the portion region of the portion capsule, to regain improved turbulence of the extraction liquid and by means of
"This improves the extraction process under the same conditions, for example, such as material thickness and the like. Another advantage is that
It is easy to generate a mechanical identifier or a "mechanical adjustment that matches an adjustment tool that belongs to the device for producing a drink. According to the invention, it is an additional advantage that, for example, a gear wheel, which is attached to the device to produce a drink and is, for example, located in the region of the product chute or similar, it may possibly interact with the gear wheel contour of the portion capsule, so it is possible to generate a mechanical adjustment 10 that allows individualize the portion capsule as appropriate and / or specify the type of portion capsule and / or rotate the portion capsule around a geometric axis of rotation, which is perpendicular to the main plane of the membrane using the gear wheel arrangement. Such an embodiment of the invention makes it possible for the portion capsule to always be opened with the device to produce a drink at the same "point (with respect to its angular position) and therefore the raw material is extracted in the same way. Even more so. the grooves prevent the portion capsule from being inserted into the coffee machine In a preferred version of the invention, there is provided that there is a flange / edge region being deflected from the bottom region, to fix the membrane on the base element, where in the wall region between the flange / edge region and the bottom region preferably has an edge and the grooves are preferably being extended to this edge because of this is another advantage according to the invention by one side the wall region can be built in a stable and reinforced mode and on the other hand the gear wheel-shaped contour of the grooves, located in the wall region, is able to absorb a relatively high load. and the portion capsule can be rotated easily and without any damage to the portion capsule within the device to produce a beverage. Preferably, the diameter of the base element is increased in the edge region compared to the wall region, which extends from the edge to the bottom region.
This gives rise to the advantageous possibility of stacking the portion capsule or the base elements of the portion capsule easily and rapidly.
Furthermore, it is preferred that at least part of the grooves 5 are in the form of a gear wheel and at least one plane, which is at least partly in the form of a gear wheel, is parallel to the membrane such that the contour in gear wheel shape expand over the edges or the flange / edge region.
Additional preferred versions of the present invention refer to 10 portion capsules that implement one or more of the following characteristics: - the base element tapers towards the flange in the edge region, - the grooves directed towards the bottom region expand 15 over the edge region, - the grooves cover approximately 20% - 80%, preferably 4Ô ° / o - 60 ° 6 of the wall region, which is placed between the edge and the bottom region, - the grooves are constructed in such a way that the wall region is reinforced and / or the groove causes a turbulence of the extraction liquid within the cavity.
Other preferred versions of the present invention relate to portion capsules that are manufactured in such a way that the ratio of the diameter of that wall region of the base element which is contiguous to the flange and the flange diameter is between 0, 85 and 0.89, and specifically substantially 0.87. In a preferred version the diameter of the wall region, which is adjacent to the flange, is 39 millimeters and the flange diameter is 45 millimeters.
Another advantageous version of the invention prefers a base element that has a thicker wall region in the edge region compared to the wall region between the bottom region and the flange.
Like the design of the portion capsule, which contains grooves in the wall region,
"improves its stability, it is possible to save material by making the portion capsule and therefore reduce the cost and energy required to manufacture the portion capsules.
According to the invention, it is further provided that a fi lter element is disposed within the cavity.
Such a filter element divides the cavity into a first region to accommodate the raw beverage material and a second region to accommodate a beverage extract.
Specifically, it is provided that the filter element is made of a non-woven material. According to an additional subject or preferred development of the present invention, the portion capsule according to the invention is intended for the preparation of a hot drink.
The invention is explained below on the basis of Figures 1-22. These explanations do not restrict the general idea of the invention. 15 Figure 1 shows a portion capsule that contains sections that differ optically.

Figure 15 shows a portion capsule that contains a section, which is electrically conductive, on the wall.
Figure 16 shows a portion capsule with a gear wheel placed inside the preparation chamber.
Figures 17a-c show different modalities of the portion capsule according to Figure 16. Figure 18 shows the portion capsule according to Figures 16 and 17, when the portion capsule is mounted by locking with a gear wheel.
Figures 19 and 20 show a schematic view of a portion capsule according to an embodiment of the present invention, Figures 21 and 22 show two cross-sectional views of the portion capsule according to an embodiment of the present invention.
The view illustrated on the right side of Figure 1 shows a portion capsule 1 comprising a base element 2 having a wall region 2.1 and a bottom area 2.2. The wall region 2.1 and the bottom area 2.2 define a cavity, which can include the raw material and perhaps an embedded element.
After filling the cavity is sealed by a membrane, which is preferably attached to the edge region 2.4 of the base element using a seal or glue.
This portion capsule can be inserted into a preparation chamber shown in Figure 12, with a liquid, specifically water, that flows through it.
During this process the raw material is extracted or dissolved and therefore the drink is
"reduced.
According to the invention, the portion capsule has only one identifier that allows determining whether the respective portion capsule fits and in the preparation chamber of the coffee machine and the parameters for processing are chosen appropriately.
If this is not the case, problems
5 but with significant security, the insertion of the wrong portion capsule, for example, endangers the tightness of the preparation chamber.
In this case, hot water can be discharged under high pressure and therefore compromise the safety of the user.
Otherwise, it is also possible that the insertion of the wrong portion of the capsule will damage the
10 coffee.
In this example, the identifier is represented by several "raised" areas, which differ in the reflection properties of the sections between the raised areas.
As shown by the arrows, the protrusions are passed through a detection means (here: an optical detector) that is able to differentiate between unequal sections 5, 6 that have different properties
15 optics such as, for example, reflection.
The change between the different sections "or the number of protrusions represents the identifier.
After the identifier has been read, the identifier is compared with a stored reference.
If the identifier agrees with the reference, the coffee machine will start to operate.
Specifically the pump, which is, for example,
20 responsible for pushing the hot water through the preparation chamber, will not start to operate, if the identifier does not agree with the. reference.
All notes regarding the identifier apply to all examples.
Figure 2 shows another embodiment of the
25 according to the invention.
Here the portion capsule has a bar code placed in the area of the upper surface of the membrane.
This barcode can be printed by removing material or it can be generated by means that is integrated in the pehcula and can be detected optically such as a fluorescence agent.
Alternatively metallic rings can
30 be part of the pellule or be attached to the film.
The barcode section can be made of ferromagnetic material.
As shown by arrow 15 the barcode may alternatively be stuck in the region of
"edge of the base element deflected from the membrane, such a bar code is read by a detector 13 placed, for example, inside the product track. d
The bar code represents the identifier according to the invention.
Figure 3 shows another embodiment of the
5 according to the invention.
In the present case the identifier comprises ridges and protuberances, which result from material removal or remodeling of the portion capsule as shown here by the example of wall 2.1 of the portion capsule.
In the present case, the recesses and protuberances interact with a detection means 13, which operates as a key, in
10 that the coffee machine only starts to operate, when all elements 13 are placed inside the respective recesses.
Therefore, an electrical circuit can be changed or specially closed.
Figure 4 shows an embodiment of the portion capsule endo being substantially identical to the embodiment illustrated in Figure 1. As a
In the alternative version of the invention, the figure furthermore shows that sections that differ in terms of optical properties can be attached to the cover film, for example, in the form of a bar code.
Figure 5 shows a portion capsule embodiment being substantially identical to the embodiment illustrated in Figure 3. Again the
20 recesses represent the key bit.
The coffee machine will only start to operate if the recesses interact with the corresponding protrusions and therefore an electrical circuit is changed respectively.
The placement of such a system is not restricted to the preparation chamber.
For example, the system can be placed on the product chute of the portion capsule. Figure 6 shows a version of the invention that includes an electrical material that forms a surrounding ring, which preferably has a high shape.
The electrically conductive material is scanned by sliding electrical contacts, which are placed inside the product trough and form electrical contacts of an electrical circuit, while the
30 portion is inserted.
Figure 7 is a modality of the portion capsule, being substantially identical to the modality illustrated in Figure 6, in which it is provided.
"than the ring area has reflective or matte sections, for example, in the form of a cover, and allows a reading through optical detection,,
These are placed inside the product trough and are part of a control chain, while the portion capsule is inserted. 5 Figure 8 shows a relatively broad and raised ring which represents the identifier. The product trough is equipped with a corresponding gap that tests whether the portion capsule has the appropriate identifier. The wide ring is scanned, for example, by mechanical sensors, which are placed inside the product rail and close the contacts of an electrical circuit, while the portion capsule is inserted. Figure 9 shows another embodiment of the portion capsule according to the invention. In the present case, an electrically conductive coating is integrated into the back of the edge region and is scanned by sliding electrical contacts, which are placed inside the product box and form the electrical contacts of an electrical circuit, while a. portion capsule is inserted. Figure 10 shows another embodiment of the portion capsule according to the invention. In the present case the portion capsule has an electrically conductive coating ta! such as a layer of conductive varnish or aluminum foil. The coating is scanned by sliding electrical contacts, which form the electrical contacts of an electrical circuit, while the portion capsule is inserted. Figure 11 illustrates a version of the portion capsule that also has an electrically conductive coating that is placed on its bottom and is identified by a metallic sensor, which is placed inside the channel and, for example, inductively detects , while the portion capsule is inserted. The embodiment of the invention shown in Figure 12 has an embedded element made of metal (here a colander 19) that is recognized as an identifier by a metal detector. The version of the invention shown in Figure 13 includes a ferromagnetic material placed at the bottom of the portion capsule. The identifier is
- scanned, for example, by a magnet, which is placed inside the chute, while the portion capsule is inserted. The ferromagnetic material acts
B as the identifier. Figure 14 shows another modality which includes a 5 bar code placed in the region of the covering film. According to the modality shown in Figure 15, a metal ring is integrated in the wall and closes an electrical circuit placed in the region of the preparation chamber. Figure 16 shows another embodiment of the 10-portion capsule 10 according to the invention. The illustrated portion capsule has a base element which is basically tapered in the present case and has a bottom region 2.2 and a wall region 2.1. The base element is provided to contain the raw material and, if necessary, inlaid elements as a filter as illustrated here. The specialist knows that the inlaid element may also include other inlaid elements. A 2: 4 flange / edge region, which is preferably circular and, for example, can be used to seal a cover film on it, is attached to the end of the base element, which is located opposite the bottom.The flange / edge region has a means for locking by adjustment, locking by friction and / or detection 2.4.2 in the outer area (outer circumference) As shown in Figures 17a-17c, the means 2.4.2 is, in the present case, a gear wheel that is formed by several bumps / protuberances uniformly arranged in the edge region. In fact, the edge region is provided with a sealing surface, 25 which interacts sealingly with the seal 21 attached to the preparation chamber 27, on the inner side of the gear wheel. The seal 21 ensures that the water coming from a water inlet 28 preferably flows through the portion capsule through an opening, which was made by a mandrel 29, instead of around it. 30 Figures 17a-17c show different modalities of the medium
2.4.2. According to the version shown in Figure 17a the gear wheel has forty-five teeth- According to the version shown in Figure
- figure 17b or 17c the gear wheel has twenty-two or twenty-nine teeth, respectively. The specialist knows that manufactured teeth can
W be formed arbitrarily. All Figures 17a-17c demonstrate how the portion 1 capsule can be retained by part of the preparation chamber 27 using two retaining arms 30. The retaining arms interact with the medium 2.4.2. If these are not available, the retaining arms do not retain the portion capsule and the portion capsule will not be inserted into the preparation chamber and will fall through it into a drain box instead. 10 Figure 18 shows the 2.4-2 means together with a "locking by means of adjustment 24, which is attached to the coffee machine and is represented here by a pinion. The means for locking by means of adjustment 24 is provided inside. the product trough that has a door for inserting the portion capsule in the coffee machine. The distance between the inner wall 15 of the portion capsule 25 and the pinion 27 is designed in such a way that the portion capsule will only pass through the door, if the means for locking by adjustment is formed complementary to the teeth of pinion 27. Only in this case the portion capsule rotates pinion 24 while it falls. Both the rotation and the fall are represented by arrows in the figure. of rotation to pass through the product trough door and fall into the desired position later. If the portion capsule has no means or the wrong means for locking by adjustment, it will be impossible to place the portion capsule through the the product track in the desired position. In addition or alternatively it is provided that the pinion 24 25 has a pickup that detects the rotary movement and transmits it to a control unit. If the rotation at least corresponds to a defined rotating element, the control unit will activate, for example, the preparation unit. The skilled person knows that the edge of the portion capsule may include a friction locking means that interacts with a means, for example, an edge, and displaces it in such a way that the displacement is detected and therefore the preparation is activated. The specialist further knows that a sensor, being, for example,
-
For example, a camera, which detects the shape of the medium 2.4.2, can be installed inside the product track.
In the present case the shape and / or the distance m between the teeth can be detected.
If the appropriate portion capsule was inserted, the resulting signal could be transmitted to a control unit, which activates the preparation chamber.
Figure 19 shows schematically a view of another portion capsule version according to an embodiment of the present invention.
Figure 20 illustrates the same portion capsule of a different point. out of sight schematically.
Figure 19 shows the front view of the portion capsule 10.
Figure 20 shows the portion capsule viewed from a "low" angle.
In all the figures the portion capsule is identified with the reference symbol 1. The portion capsule substantially has a stem-conically formed base element 2, which is shaped similar to a pot and contains a cavity 3 Cavity 3 is sealed by a membrane 15 4. As the viewing direction of Figure 1 is essentially parallel to the plane on which the membrane is located, the figure only outlines the membrane on the upper edge of the portion capsule.
Specifically, the base element 2 comprises a soft, semi-rigid or rigid plastic material which is preferably deep drawn.
The membrane comprises a '20 pehcula made of plastic or aluminum material.
Preferably the base element has a circumferential mounting flange 17 in the region of the member, with the membrane and mounting flange 17 being firmly adhered, specifically by welding or gluing.
Preferably a filter element, which is not specifically shown in the figures, is located within the base element 2. For example, the filter element is made of thermoplastic resin such as, for example, polypropylene.
The filter element could also be made of a non-woven material such as, for example, a thermoplastic resin.
Preferably, the filter element divides cavity 3 into two sections.
It is provided that the first section can be filled with raw material and the second section can be filled with and specifically collecting a drink extract, which is not shown, during the extraction process.
Both sections are not illustrated individually.
mind. The portion capsule is intended for insertion into a chamber. preparation chamber or a device for producing a drink, which is not shown here. Specifically, such a device for producing a beverage is a coffee machine. The device for producing a drink could also be a machine that produces a tea drink, a chocolate drink or any other drink. Preferably an extraction liquid, which is specifically water or hot water, is brought under high pressure into the preparation chamber of the device to produce a drink. The extraction liquid interacts with the raw material of the beverage in such a way that an extract from a beverage or beverage is generated. Specifically the filter element is used as a strainer for the extraction of a beverage.
- According to the invention, the base element 2 has a wall region 12 and a bottom area 11. The wall region 12 basically reaches from the flange 17 to the bottom region 11. Several grooves 15 are placed in the wall region. Specifically, these grooves are keyways that are integrated in the wall region 12 and are facing the cavity 3 and reach from the flange 17 to the bottom region 11 (i.e., these 20 run perpendicular according to Figure 19). According to the invention a provision is made for the grooves 15 to be extended vertically through the wall region, that is, they run straight from the flange 17 to the bottom region 11, in which it is not necessary that these be extended over the entire length. The grooves are formed according to the invention in such a way that the wall region is reinforced or stiffened due to the grooves 15. Furthermore, the pIurality of the grooves 15, which are distributed over the wall region 12, performs a adhesion between the wall region 12 and the wall of the device preparation chamber to produce a drink after the extraction process. This makes it easier to automatically eject the portion capsule from the preparation chamber. The portion capsule version shown in Figure 19 comprises a circumferential edge 16 that is placed in the wall region 12 that alters
the flange 17 to the bottom area 11, namely adjacent to the flange 17 that faces towards the bottom area 11. The edge 16 has an increased diameter (parallel to the membrane 4) compared to the wall region al - extending from the edge 16 to the bottom area 11- It is provided that the contour 5 of the edge 16 is designed in such a way that the diameter of the edge tapers in the direction of the flange 7. It is provided according to the portion capsule mode
. which is shown in Figure 19 and in accordance with the invention, that the grooves 15 are placed in the region of the edge in the first part, partially reaching from the edge 16 to the bottom area 11 through the region of "wall 12" , in the second part and then finally they end.
In all, the grooves cover, for example, approximately 50 ° / o of the extension of the region of wall 12, which reaches from the flange 7 to the bottom area 11, in which one third of the groove station is placed in the region edge and two thirds of the slot extension 15 are placed in the remaining wall region 12 that reaches from the edge 16 to the bottom area 11. A portion capsule according to the invention is shown as a sectional view along of the extension of the portion capsule referring to its height in Figure 21, that is, the section pane is perpendicular 20 to the main plane of the membrane.
Figure 22 also shows a portion capsule according to the invention in a sectional view that depicts the section pane, which is parallel to the main plane of the membrane.
It is noted that the interior of the portion capsule cavity is shown in Figure 21. The material of the portion capsule or the material of the base element is so thin that the implementation of grooves on the outside shown in Figure 19 leads to convexities and impressions corresponding inside.
Figure 22 specifically illustrates the gear wheel shaped contour that results from the insertion of grooves in the portion capsule wall region.
